VoltageRegulator Module, 5V, 1A peak
... VoltageRegulated Module This is a highly stable linear-low-drop voltageregulator. With 12V DC input, output is 5V and provides up to 1A of output peak current. For negative voltage, you can reverse Output and ... to draw no more than 50-60% of the published peak rating. Heat-sinking the regulator may help increase these numbers. Should you see these numbers exceeded, the voltage will drop.
